Wesland Farm – Off-Grid Solar System
Wesland Farm in Porterville/De Hoek installed a 45 kVA off-grid solar system with a 52.2 kWp solar PV array and 100 kWh LiFePO4 battery storage to achieve complete energy self-reliance for its agricultural operations.

The challenge
Due to its remote location and dependency on the electrical grid, Wesland Farm found a reliable power supply and rising utility costs increasingly unsustainable for its daily agricultural operations.
The SSS solution
Specialized Solar Systems engineered and installed an off-grid solar energy system featuring a total 52.2 kWp solar PV array (22.2 kWp managed via dual 450/200 MPPT solar charge controllers and 30 kWp coupled with Fronius inverters) and 100 kWh of LiFePO4 battery storage (80 kWh usable). Power delivery is driven by 45 kVA of off-grid inverter capacity to ensure seamless energy management.
Results and benefits
The off-grid installation provides a continuous, reliable power supply for essential farm equipment and operations. Designed for future growth, the system includes a planned doubling of capacity for upcoming expansions and achieves an estimated payback period typically under 6 years.
